Hugh Pickens writes writes: "The NY Times reports that while online college classes are already common, on the whole, the record is not encouraging because there are two big problems with online teaching. First, student attrition rates — around 90 percent for some huge online courses — appear to be a problem even in small-scale online courses when compared with traditional face-to-face classes. Second, courses delivered solely online may be fine for highly skilled, highly motivated people, but they are inappropriate for struggling students who make up a significant portion of college enrollment and who need close contact with instructors to succeed. Research has shown that community college students who enroll in online courses are significantly more likely to fail or withdraw than those in traditional classes, which means that they spend hard-earned tuition dollars and get nothing in return. Worse still, low-performing students who may be just barely hanging on in traditional classes tend to fall even further behind in online courses. "Colleges need to improve online courses before they deploy them widely," says the Times. "Moreover, schools with high numbers of students needing remedial education should consider requiring at least some students to demonstrate success in traditional classes before allowing them to take online courses." Interestingly, the center found that students in hybrid classes — those that blended online instruction with a face-to-face component — performed as well academically as those in traditional classes. But hybrid courses are rare, and teaching professors how to manage them is costly and time-consuming. "The online revolution offers intriguing opportunities for broadening access to education. But, so far, the evidence shows that poorly designed courses can seriously shortchange the most vulnerable students.""

The first isn't a real problem. When you have lower barriers to entry, you have more exits. Students figuring out it's not the right class for them and bailing isn't a bad thing.
Second, the problem is underprepared students from shitty public schools. The solution is make high-school grads more college ready, not to make college high school 2.0.
